Whose Devil's Undercover Agent Is Upright?

"You said you are an undercover agent of the Demon Sect?" "Yes." "What kind of evil skills can you do?" "Hidden Demon Technique." Shen Yan activated his skills, the evil-suppressing bell rang seven times in a row, and his awe-inspiring righteousness soared into the sky. Elder Taixuanzong was silent for a long time, then slapped his hand on the table: "That's nonsense! Whose magic sect's undercover agent is upright?" Shen Yan also wanted to know. He passed through the magic gate and was sent to the right path as a consumable. It just so happens that every evil skill you practice will become upright in your own hands. So Zhengdao believed that he was born with holy bones, and the Demonic Sect believed that he was perfectly disguised. Shen Yan originally just wanted to save his life and receive two monthly payments. Later, both parties felt that it was a bit unfair to him to only issue monthly reports.
